Neil certainly earned himself a place in history unlike that of anyone else. One day a new batch of astronauts (from whatever country they are going to be) will walk on the moon, but that will not mitigate the achievement of the Apollo astronauts and the many, many who worked with them.

Actually, what he did is bigger than just the moon. He opened up possibilities, he proved that we, humans, can breach the atmosphere and stay IN space. The MIR space station would not have been possible without the Apollo crew. Opportunity and Curiosity would not be possible, without his and his crews contribution.

RIP to a legend, and an inspiration. One of the ones who enabled a whole generation to dream, and enabled the dreams of a whole generation. To understand the importance of Neil Armstrong I like to listen to Neil deGrasse Tyson's words on NASA, the Apollo program and the Moon landings.
